Ref Manager 11 in Word 2016

I got a new PC installed at work and it’s Windows 10 (with Word 2016). I still have my old Ref Manager 11 and the database, but cannot link it to Word. Tried to go to Word/Options/Add-in/Go… but no luck.

IT guys here didn’t have any quick solutions (still looking). 

Any advice? 

Thanks

(thought about switching to RefWorks, Endnotes, or Mendely, but my database is huge and I don’t want to ‘start over’ inserting refs one by one for manuscripts being revised or grants I need to update)
